ABSTRACT:
A multi-conductor parallel array armored electrical power cable includes a pair of longitudinal spring members. The longitudinal spring members help maintain compactness between conductor assemblies within the power cable after a protective armor has been applied. The longitudinal spring members are installed between the outer most conductors and the armor of the cable. The unique shape of the spring members along with their placement during assembly absorb much larger tangential forces normally accepted when applying the armor to the cable. The spring members become distorted from their original shape and, as the armored cable is further formed to its final shape, the longitudinal spring members substantially return to their original shape to urge the conductor assemblies together.
